xingtanzjr opened a new pull request, #7421:
URL: https://github.com/apache/iotdb/pull/7421

   ## Description
   In MultiLeader consensus, if a leader transfer to follower, the wal files may won't be deleted due to the reason that `SafeIndex` is not set to the latest one.
   
   In this PR, we change two places to solve this issue:
   1. update the `SafeIndex` to the latest one to WALReader rather than keep it the same as the persistence value in IndexController
   2. When finding an entry which is already deleted in WAL files, the WALReader will return the minimum one whose searchIndex is larger than the target entry
